The common cable broadcast network delivers multimedia content to a large number of 2 household cable networks. Cable networks typically include a headend and a distribution node. Each: the head end receives programs from various sources, generates independent modulation for each program = number, multiplexes the modulation signals of all programs to the output signal and sends its output signals to the distribution node. One (the coronation A mother-in-law can be assigned to a large geographical area (for example, the entire country) or a smaller geographic section of the Et ghost test. For example, the domain city). Each of the allocated geographical areas (for example, 'community') receives the output signal from the head end, and multiplexes the modulation signal S τ m of the program to be overwritten by each of them. Distribution J: * J 〇 on the same channel and send its output signal to the occupants in the coverage area. Each _ home program and regional program, ... / out of the usual carrier country, which is usually on the The signal is transmitted on the independent modulation signal. 9 Output signal: The line broadcast network wirelessly transmits the data to the wireless device. However, the coverage of the helmet is the cable broadcast network in the domain. The aspect can be different from finding one of the different aspects. ju ij. The user is mobile, and the direct result is: the end of the radio distribution system, defying the user (almost by definition), Point (for example, in a residential or commercial location). Because the H0278.doc 1327444 wireless user is mobile, the location of the user can change from the coverage area of the broadcast network to another broadcast network. The coverage area. If two broadcast networks The road broadcasts exactly the same content on exactly the same channel, so the user can easily switch from one network transmitter to another (very similar to the cellular handover). However, in many cases, adjacent The broadcast network not only does not provide the same program but does not provide the same program on the same channel. Therefore, 'automatically exchanging users to the nearest broadcast network can interfere with the interactive content currently used by multimedia or users. Therefore, it needs to be effective and Consumers appreciate the way to exchange wireless users in a wireless broadcast network to another-neighboring broadcast network. [Invention] One aspect of a wireless broadcast network relates to a broadcast in a wireless communication device. A method of exchanging between networks. According to this method, a current broadcast signal is decoded from a plurality of broadcast signals, and each broadcast signal is from an individual broadcast network. If one of the plurality of broadcast signals is determined to have a higher The quality score of the current broadcast signal, asking whether one of the users of the device switches to the plurality of broadcast signals If the user chooses to exchange 'the device starts to decode the one of the plurality of broadcast signals instead of the current broadcast signal; otherwise, the decoding of the current broadcast signal continues. A different aspect of the wireless communication device is related to the device And comprising: a processor configured to determine a plurality of broadcast networks having a highest quality score. The apparatus also includes a user interface configured to receive a message from a user of the device Selecting a fate receiving state of the one of the plurality of networks, the processor being controlled by the processor and configured to be based on the command

Other embodiments of the invention will be apparent to those skilled in the art in the <RTIgt; The present invention is capable of other and various embodiments and its modifications may be modified in various other embodiments. Therefore, the schema and detailed description of the capital are for the sake of illustration and not limitation. The detailed description of the embodiments of the present invention is intended to be illustrative of the embodiments of the invention. The detailed description includes specific details for the purpose of providing a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without the specific details of the above. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring the inventive concept. Techniques for broadcasting, *like types of transmissions (e.g., regional transmissions and wide area transmissions) in a wireless wide-band network are described herein. As used herein, "broadcast ""broadcasting" refers to the transmission of content/data to a user group of any size and may also be referred to as, "multicast" " or some other term. Wide area transmissions can be broadcast by all or many of the transmitters in the network. The zone transmission can be transmitted by a subset of the transmitters for a given wide area transmission. Different area transmissions may be broadcast by different subsets of transmitters for a given wide area transmission. Different wide area transmissions can also be broadcast by different groups of transmitters in the network. Although wide-area and regional transmissions typically carry different content, such transmissions can carry the same content. An example of such a broadcast network is a QUALC 〇MM MediaFL®TM network that delivers a programming sequence with a bit rate of about 2 bits per Hz per second. The technology used is specifically designed to cost-effectively multicast a significant amount of rich multimedia content to wireless users based on an orthogonal frequency division multiplex (work) air interface. It uses multipoint technology in a single frequency network to significantly reduce the cost of delivering the same content to multiple users simultaneously. In addition, as described above, the coexistence of area coverage and wide area coverage within the single-R β ~ , Dan early RF channel (for example, 700 MHz) is supported. This segmentation between the wide area and the region supports more target programs, regional advertising, and the ability to interrupt and re-tune.

Different content providers deliver the content to the broadcast network, which then combines the content and broadcasts the content according to the predetermined M*. During the provision of the user's mobile device, the ability to receive and decode the channel to which the user subscribes is programmed into the mobile device. The supply can then be updated to remove or add other packages and channels. - Those who are familiar with this technology will understand that they have just shaken

Other configurations and organization of the data and its individual channels may be utilized without departing from the scope of the invention. 1A depicts two exemplary wireless broadcast networks 1(2), each of which may provide multiple different channels and content to multiple locations in a relatively large geographic area. user. For example, the transmission of the network 1〇2 can broadcast the evening channel and the transmitter 〇2 13〇 can broadcast its own channel within the coverage area of the network. Broadcasts from different transmissions of $12G, 13G do not have to be the same and may include different passes or different content. For example, one network can be in the Pacific time zone while other networks can be in the mountains, although the two networks provide the same channel, but the actual program can be different because the time zone difference is broadcast (for example, the main event movie is scheduled - straight In the local time, please start the PM. In addition, there are logical channels (for example, pay) and physical channels (for example, specific TDM time slots or specific frequency bands). Therefore, although the two networks 1G2 and 1G4 provide ESpN, they cannot be in the same entity. The ESPN is broadcast on the channel. The result of this lookup difference is that the access to the available content can be changed as the wireless user II0278.doc 1327444 moves from the coverage area of a broadcast network 102 to a different broadcast network 1-4. See Figure 1A. The mobile device 110 is clearly within the coverage area of the network 1〇4 and the other mobile devices 108 can detect the presence of both the network! 02, 104. As the mobile device 108 moves from the network coverage area 1〇4 to the other The network coverage area is 1〇2, and the broadcast signal from the transmission of the Ding Ding 120 will become stronger than the broadcast signal from the transmitter. Because these signals are stronger, the mobile device] Users will be provided with better service in the network 〇 2 because there will be less signal delay, signal error, etc. Therefore, it is easy to see that the best thing to do for the mobile device 1 将 8 will be the amount The signal strength from the two transmitters ι2〇, 1〇3 is measured and locked to a strong signal. This method has many disadvantages. The transition zone between the two networks is not a clearly defined area and the nearby structure can be seen. , the direction of the propagation, the weather and other similar factors. This 'as the user moves from one network coverage area to another network coverage area, the transmitter with strong signal 12〇, 13〇 can reciprocate Change multiple times until the user is sure to be in the new network coverage area. Therefore, if the device just changes to the strongest network every time a new network is detected, it can be used for the user's heart. This event is destructive in many situations, especially in the case of instant content and interactive content. Secondly, the user of device (10) may want to continue to use a particular content channel, degraded or weakened. For example, if the sporting event Being = and = last few minutes or seconds 'The user is willing to withstand the drop, and the service is 'to ensure that the final moment is seen in an uninterrupted manner. 叮 Refer to the ordering device 106 to explain another possible situation. Device U0278.doc 1327444 1〇6 appears to be clearly within the network coverage area 1〇2, but the signal from the transmitter cannot be - straightest. For example, there may be a building between the device and the transmitter i2〇 Or other structure, which produces a "shadow" of the receiving device. In this shadow, the signals from other transmitters I 13 can actually be perceived as stronger signals. Therefore, if switching to different networks Instantaneous and automatic, device 108 can lock onto a different network as it enters and leaves the shadow. The network diagram of Figure B depicts another scenario in which a mobile device can transition between different networks. In this example, three transmitters (along with other transmitters not shown) transmit signals over the area that produces the wide area network 49. Within this region 149, there is a constant set of identical content for the entire region. This is true even if the mobile device is in one of the three regions 150, 152, 154. However, in these areas, there is a portion of broadcast content that differs between different networks 15, 152, 154. Thus, each network ι, 152, 152 has its own unique regional content that is transmitted by the transmitters 151, 153, 155 along with the common wide area content, respectively. As the device and 162 move through the wide area network M9' wide area content will remain the same and the regional content may be different. Thus, similar to the situation described with respect to Figure 1A, there may be situations in which it is advantageous to exchange between different adjacent networks and there may be situations in which exchanges should be avoided. Typically, the transmitters 151, 153, 155 will acquire, decode, and decode the signals for 5 weeks to extract the desired content. In the OFDM system mentioned earlier, these signals may include wide area content data, regional content data, additional information, and timing signals. Timing signal (often referred to as a pilot signal) by action

The content material can be divided into different channels and broadcast at independent times or frequencies (depending on the encoding method). Additional information can be used by the mobile device to determine which portions of the broadcast signal to decode. For example, if the user only needs to receive one of the 20 or 50 channels provided, the mobile device can use additional information to demodulate and decode only portions of the broadcast signal associated with the desired channel. Performing in this way provides effective power usage and extends battery life. '

For example, the data symbol for wide area transmission can be multiplexed to the "transmission span" configured for wide area transmission, and the data symbol I for transmission in the area can be transmitted. For transmission spans configured for regional transmission, TDM and/or reward for wide-area transmission may be multiplexed to the transmission span configured for such indications, and may be used for regional transmission. TDM and/or fdm direct multiplexes to the transmission span configured for such indications. Additional information for regional and wide-area transmissions can be multiplexed to - or Multiple specified transmission spans. Different transmission spans can be used for different frequency sub-bands (if FDM is used by the radio broadcast network), (2) different time periods (if using Ding) DM) or (3) different Js in different time periods and sub-bands (if both TDM and FDM are used). The following describes various transmission mechanisms. It can also handle 'multicast and broadcast with Two or more different types that do not differ from each other due to different levels of coverage Type of transmission. In the wireless broadcast network, the hot device performs supplementary processing to restore the area for transmission and wide area transmission. M027S.doc -13 - 1327444 Figure 2 shows the broadcast area transmission and widening in the OFDM-based wireless broadcast network. The exemplary hyperframe structure 200 of the domain pass 200 is referred to as unit t of the superframe 210. Each hyperframe spans a predetermined duration, which may be based on various factors such as the statistical multiplexing required for the stream being broadcasted, the amount of time diversity required for the data stream, the time of acquisition of the data stream, the buffering requirements of the wireless device, and the like. Choose it. A one-second superframe size can be used to make good choices between the various factors mentioned above. However, other super frame sizes can also be used. For each of the embodiments shown in FIG. 2, 'Every Super Stick 2' includes the header section 220 not shown to scale in FIG. 2, four equally sized frames 23〇a to 230d and the tail.

A pair of TDM guides 201 are transmitted at or near the beginning of each superframe and can be used for the purposes described in Table 1. The transitional indication is sent at the boundary between the zone block/transport and the wide area field/transmission and allows for a seamless transition between zone placement/transmission and wide-area field/transmission. Area transmission and wide area transmission can be used for multimedia content such as video, audio, telex, data 'video/video clips and the like and can be transmitted in a separate data stream. For example, a single multimedia (eg, 'TV') program can be used to send three separate streams of video, audio, and data. The data stream is sent on the data channel. Each data channel can carry _ or multiple data streams. The data channel carrying the data stream for regional transmission is called "area channel", and the data channel carrying the data stream transmitted by the wide area is called "wide area channel". The area channel is in the area data column. The data is transmitted in the bit and the wide area channel is sent in the wide area data shelf of the super frame. Depending on the payload used for the data channel, the availability of the interlace in the hyperframe, and possibly other factors, each data channel can be In each of the Super Kings, the IU疋 or variable number of interlaces are configured. Each data channel is in the following:: The super message frame can be active or non-current... Each active data is used: Two: One: One less interlaced. Based on Trial round (1) as efficiently as possible: the current tributary channel, (7) reduce the transmission of each data channel = the time diversity of each data channel and (4) minimize the need to interleave the allocation of the parent-data channel The distribution of the signal quantity (4) The data channel is also used in the super frame. In the case of the current data channel, the mother-J can be used with the M027S.doc 1327444 frame of the super frame. The bit indicates the time frequency allocation for each active area channel of the current hyperframe. The wide area OIS field indicates the time frequency allocation for each active wide area channel of the current hyperframe. Area 0IS and wide area 〇13 Transmitted at the beginning of each hyperframe to allow the wireless device to determine the time-frequency configuration of each data channel of interest in the hyperframe. The multiple fields of the hyperframe can be in the order shown in Figure 2 or some Other sequences are sent. In general, TDM citations and additional information need to be sent early in the super message box so that the job citation and additional information can be used to receive the information sent later in the super message box. The transmission is as shown in Figure 2) or after the area transmission, the wide area transmission is sent. Figure 2 shows the specific superframe structure.

For the sake of clarity, 'Circle 3 shows data processing by area transmission and wide area transmission performed by base station 1 (HG and wireless device deletion of two different data processors. Data processing for all types of transmission can be performed by the base The single data processor at each of the wireless devices 1050 is implemented. Figure 3 also shows the processing for two different types of transmissions. In general, any number of types with different coverage areas The transmission wheel can be transmitted by the base station and can be received by the wireless device 1050. For the sake of clarity, Figure 3 also shows all of the units of the base station 1〇10 located at the same location. In general, such 110278.doc • !9· 1327444 Units can be located at the same or different locations and can communicate via various communication links. For example, 'Data source 1〇12 and purchase can be located away from the site, transmitter unit】 032 and/or antenna 1〇34 can be located at the transmission site, etc. User interface 1094 also communicates with controller ,9〇, which allows the user of device 控制5〇 to control the mode of operation thereof. Word, interface ι〇9 4 may include a keypad and an underlying hardware and software-based display that is required to prompt the user to enter commands and instructions and then process the commands and instructions. For example, the user interface 1〇94 can be used to inform the user that the new network is providing better signal strength than the current network and is used to query the user device 1G5 (^ should be able to acquire the new network of the network) WIC/LIC information and a score or value indicating the quality or strength of the signal. A flowchart describing when the mobile device should change from one broadcast network to another exemplary method of wide network. In step 402, the action The Y/Hanger is also operated and based on the currently selected service broadcast network demodulation and decoding degraded No. 7 demodulation and decoding based on TDM pilot signals providing timing information and channel estimation (and possibly other references) Marking) ° During the untwisting, errors can occur and the use of error correction codes and other techniques can be used: witness, ^. Due to the uncertainty of the wireless environment, even in the correct operation of the 'Ding' system also A certain amount of error can occur. Therefore, a threshold that defines an acceptable error of μ 勺 is usually selected. This acceptable number of errors can be based on the entire Hyperframe or each individual frame based on the inside of the Hyperframe. > - A positive value can be "16 errors in the entire superframe or less than 16 I10278.doc 1327444 errors" and another threshold can be, in any individual frame There are only two errors. In addition, the threshold can be the ratio of wide-area data to regional data, so that more errors are allowed in the regional data than in the wide-area data. In any case, the general reviewer will understand There are many different ways to measure and determine if the predetermined error threshold has been exceeded. If more errors than the allowed number are obtained (in step 404), the software running on the mobile device causes the demodulator to regain the current signal (in step 4-6). This re-acquisition can be a new acquisition from scratch or it can be partially recovered using some of the previously detected benex. For example, an advantageous way to regain a signal using the 超级2 superframe is to attempt to regain WIC/LIC, TDM2, and 0IS. Based on the regained information, the timing resolution for further demodulation and decoding can be improved. This step will likely correct any problems caused by timing issues only. In step 408, the mobile device continues to demodulate and decode the material from the current serving network. At the same time, in step 41, the mobile device obtains all the signals it can detect and generates a score indicating the quality of each signal. Advantageously, the number of samples for the mother signal is greater than one, so that the quality of each signal is The score is based on the combined scores of the different samples for each signal. For example, 5 samples (or more or less than 5 samples) of each signal can be measured and the individual quality scores of each signal sample can be averaged to produce a combined score of the signals. Use the Superframe in Figure 2 to get WIC/LIC, TDM2, and OIS for all detectable network candidates. Based on the pilot signal and/or other signals, a quality score can be assigned to each WIC/LIC. As mentioned, this quality score can be generated from each WIC/LIC by detecting multiple hyperframes. In step 4丨2, a determination is made as to whether the WIC/LIC of the current serving broadcast network is the top network (based on: Bayesian score) of the list of network candidates determined in step 410. If the top network in the candidate list is different, the choice to switch to the new network or stay on the current network can be presented to the right user. The quality of the received signal can be reduced, but it will continue to crack. decoding. Eventually, the signal can become too degraded and the signal will be lost. ° In step 414, if the user selects the switching network, the mobile device executes the new network command ^ 卩 你 " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " " Take the TDM1, WIC/LIC, and (10) of the new network to start demodulating and decoding the broadcast signal. The above method prevents the R effect exchanged between the previously described phases from being selected and not exchanged in at least two different ways. 'Make::: The network is automatically switched from one network to another, although the two (4) and the second heads can be additionally proposed for the strength of the t. The second is in many samples, and the mouth is: The temporary anomaly in the signal strength is ignored so that == 4°, therefore, the exchange between the two networks can still occur effectively, but can be performed in a manner that the user appreciates. Figure = Principles in accordance with the present invention The "white layer" of the operable mobile device 500. There is a decision component 502 that determines an individual quality score for each of the plurality of broadcast networks. This also decodes the possibility of having a specific broadcast network that can be successfully received by the stomach dW. The device 500 also includes a command to receive the user or operator of the folder i from 5 〇 0. The command is related to whether the user is willing to exchange a broadcast network from a broadcast network. The receiving member 5.4 and the junction of the determining member 5 〇 2 I I0278.doc 4 are supplied to the decoding member 5G6. (4) In other words, the decoding component can encode which broadcast network signal. For example, the decoding component can maintain its selection and continue to receive and decode the current broadcast network signal. Alternatively, if so ’, the decoding components can be exchanged such that they receive and decode a different broadcast network signal having a river DP quality score. Therefore, the mobile device 5 〇〇 = to allow the user to input as an element of the device from one broadcast network to another.
